manifold for use with such lavatory or ventilating device, which can be readily applied to a toilet seat with the usual fastening means for the seat and in such a manner as to entirely close the space between the seat and bowl, to

"efliciently conduct the vapors therefrom, and is a division of my prior application, Serial No. 207,681, filed May 13, 1938, now matured into Patent No. 2,167,152. 0

Among the objects of the invention are to pro- .,position as to be protected from thewater; which canbe applied without alteration of the structure of the flush apparatus, and which includes an exhaust or suction. fan operated by an electrical motor also protected and hidden from view, the

motor and fan being normally inoperative when the seat and cover are lowered or closed, and

rendered operative when the seat is raised or opened, while the fan has a damper also closed fan in operation by closing a normally open elec-' trical circuit to the motor, whereby to exhaust the vapors to a suitable stack as between walls of a building for conveyance to the outside atmosphere.

Other objects and advantages will appear and be brought out more clearly in the following specification, reference being had to the accompanying drawing, wherein:

Fig. v1 is a side elevation, partly, broken away and in section, showing my device applied;

Fig. 2 is a plan View, also partly broken away and in section;

Fig. 3 is a detail horizontal sectional view of the suction intake manifold;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2; and l Fig. 5 is an enlarged detail sectional elevation taken on the line 55 of Fig. 2, and showing one form of switch for controlling the operation of the motor.

Referring more particularly to the drawing,

wherein the device is shown applied, I 0 is a bowl having the rim II with a flush water passage 12 with discharge openings 13, horizontal rear inlet extension M with side flanges or vertically apertured ears l5 and connection or coupling 16 to a water supply or flush pipe ll receiving its supply from any suitable valved controlled means, such as a low flush tank 18 coupled thereto as at l9.

The bowl is provided with a seat section 20 hinged by brackets or leaves at 21 to posts 22 clamped through apertured flanges or ears I5. Between the seat 20 and bowl rim H from which it is slightly spaced, is a rubber or like packing or cushion 23, while a seat cover section 24 is supported when closed on seat section 20 with interposed cushions 25, and also hinged at, 2 by brackets or leaves on a pintle common to both sections to swing up and down toward and away from the flush control or. tank 18 in the usual manner common in the art.

This structure is standard and may vary in details according to the type of flushing apparatus a wall 26 of a building, with inner and outeror spaced portions or walls 27 and 28 forming a stack or air space 29 therebetween communicating with the atmosphere or otherwise ventilated.

In connection with myinvention, the cushion 23 is omitted between the bowl H] or, rim ll thereof and seat 20 at the back on the horizontal shelf extension and flange l4l 5 in the space which receives, and below the hinge or pintle leaves or brackets attached to the seat 20 at the bottom, as shown, and pivoted to "a common pintle 2| also provided' for the hinge or pintle leaves or brackets attached to the bottom of the cover 24 and received on the bowl rim in the space between saidbowl and seat. In this space is positioned a hollow suction intake manifold 30, which, however, may be thinner than the space so that the'top face of the manifold is spaced from or in close proximity to the bottom face or fixture installed, but the tank is shown against Y of the seat and hingebrackets or leaves of the seat, as shown at 31 in Fig. 1, so that no pressure will be exerted thereon by theiseat, although this is optional.

The manifold may beof suitable non-rusting material such as aluminum, fibre, wood, white metal, brass, iron, hard rubber, Bakelite, synthetic or plastic composition, or otherwise, or may be of rubber or cushioning material of sufiicient hardness not to compress or flatten' out, or, if of rubber or soft, or formed to fit a recess or cut out in, or as part of the cushion 23,,the seat. may be supported from the bowl in spaced relation, in. close proximity. to, or just touching the.

overv the intake d5.

top of the manifold. A casting of rigid or hard material is. preferred, such as aluminum.

As shown in Figs. 1, 2 and 3, said manifold has an open concaved forward or inner edge 32 set back in spaced relation from the inner edge of the bowl, ledge or rim l to prevent the water from entering or splashing into the same, but the top and bottomiwalls are reinforced by spaced division, walls, webs, or spacers 3% at said curved open inner side or forward edge 3'2, which may conform to the curvature of the bowl and seat, or. be eccentric thereto. The ends are closed as by inwardly curved flanges 34, and the outeror rear side or edge is closed as at 35 and terminates in. a tapered outlet or neck coupling portiondfi gradually increase in thickness to tubular form: and round cross section and: extending toward one side around or so as to clear the pipe ill For this purpose, one side of the neck 36 extends at an obtuse angle and the other side atan acute angle, .and the end maylbe .reduced to form a nipple as at 3'2, or extendedas far as-necessary to. connect with a suitable ventilating means or suction fan 38 as will be more fully explained.

The casting or manifold has side flanges or a v bottom plate extension 353 at the back to. rest on. the top of ledge M or flanges i5 and provided withapertures or slots dihpreferably'enlargd or elongated transversely to accommodateand;

receive the threaded stems ofv the forwardly; curved posts or stud bolts 22 to secure themanifold in position by nuts 4!, and washers 42 are interpcsedbetween the enlargements or flanged heads of the posts and flanges or platetii, and between the latter and the flanges E5 or top of the bowlnwhichis usually of vitrious material. Such washers 42 are also interposed between the bottom of the flanges i 5 andthe nuts ll threaded on the lower ends of the-posts, to prevent contact of the metal with the. bowl and securely clamp the seat and cover, as well as the manifold in position.

vThe neck or pipe SESmay' be as short or as long as desired or necessary, but as shown, in order toconnect the same to the suction fan or blower 38, a pipe extension or conduit section 43 isconnected to neck as and nipple 3'! and a nipple or sleeve extension M on the casing or housing, of the fan 38 at the axis of rotation of its impeller .45

The fan is driven by an electrical motor M, and the fan has an outlet 48. which is shown extending eccentrically in an upward direction and into the stack or space 25 or may extend through the wall or communicate with the outside atmosphere in any other suitable way. The fan and motor aresupported in an open top box or compartment 49 positioned through an opening 55 in the inner wall 21 and upon a horizontal partition support 5!, the front of the box 49 being closed by a removable cover plate 52 providing access to the fan and motor and having an opening receiving the pipe 1 3 and insulated wires 53 and 5 3 from the motor ll. The outlet {48 is provided with a damper 55 normally 3. held closed by a spring 56 connected at one end to a shaft 5'! towhich the damper plate is fixed and on the projecting end of'which the spring is mounted, while the other end of the spring is anchored to the outlet.

An arm 581s fixedto the'opposite end of the shaft and is pivotally connected to a link 59 disposed through an opening in cover plate 52 to atswitch lever arm or button 68 of a switch 6!, setin a slot in pipe 43. An armiiZ attached to theundersideofthe seat or. cover i i projects upwardly and rearwardly and is also pivotally connected to arm 66 by a link 63 properly shaped or curved to translate arcuate or oscillatory movement of the arm 62 into similar or reciprocable -movement of the arm iii] of the switch iii shown of the 2-point type. One wire 53 from the motor #31 to one of a pair of spaced insulated stationary contacts. S iofthe switchil .is. adapted to be bridged by a. movable contact 65. of'lever arm ortoggle 68 including a spring 66. The other wire 54 and a wire 37 from the other contact 64 are connected to a source of electrical energy, not shown, such as a battery, generator or a plug for fitting in a socket of the house wiring.

Obviously, when contact 65 engages contacts 64, the-circuit is-closed tothe motor to operate the fan 'orblower and vice versa when the contact is in the opposite position, as shown in Figs. 1, 2 and 5, which is the normal position when the cover is closed and arm fill is forward. However, when the cover is opened, it will, through arm 62 and link 63, move arm 6% back to closethe' switch and circuit to the motor. At the same. time, the arm 66 will move link 59 rearwardly to. swing the arm 58 and simultaneously open the damper or outlet control valve and reverse drafti control check 55, so that the vapors, etc.,..will be exhausted, and proper and thorough ventilation insured. By reason of the cover plate52, ready:- access may be had to the motor and fan forany purpose.

While I have illustrated and described the pre-* ferred form of construction forcarrying my in vention into effect, this'is capable. of variation and modification without departing from the spirit. of the invention. I, therefore, do not wish xtobe limited to. the precise details of construction-set forth, butdesire to avail myself oi such variations and modifications as come within the scope of. the appended claims;

Having thus described my invention, what I claim as new and desire-to secure by Letters Patent is:
